Fine structure in the α decay of ²¹⁹U

RADIOACTIVITY ²¹⁹U(α)[from ¹⁸³W(⁴⁰Ar, 4n), E=190 MeV]; measured Eα, Iα, αα-coin, (recoils)ααα-correlations, half-life of ²¹⁹U decay, production σ of ²¹⁹U using position-sensitive strip detectors (PSSDs) for α detection, and the SHANS separator at the Heavy Ion Research Facility (HIRFL) in Lanzhou. ²¹⁵Th; deduced levels, J, π, α-branching ratios, α-decay reduced widths. ^{216,216m,217,219}Th, ²²⁰Pa(α)[from ¹⁸³W(⁴⁰Ar, X), E=190 MeV]; ²¹⁵Th, ²¹¹Ra[from ²¹⁹U α decay]; measured Eα, half-lives of decays of the isotopes. Discussed α-decay systematics in neighboring nuclides. Comparison with previous experimental data.
